Dropped my bb 8703e into a tub of water. Dried it thoroughly. All worked except the display. Bought a replacement LCD, installed and works great. Now, a week later, suddenly, microphone isn't working. no one can hear me. If I use a microphone/ear piece thing, THAT works, so I know the problem is the mic in the bb itself. Can this be replaced? Does anyone know? I haven't found a mic part online.
